` IMPROVEMENT IN STEAM-PUMPS.

l a y SPEOIFIGATION.

I, WILLIAM` L. BORNE, of Chicago, Illinois,

` have invented certain new and useful Improvements in Pumps, of which the following is a full, clear, and exact description, reference be `ing had to the accompanying drawing making part of this specication, and consisting of' @two sheets, in whichf- Figure l is a vertical section; Fig. 2, an enlarged detail; Fig. 3, a detail ,1 Fig. 4, a side elevation, showing the siphon. j

fj My invention is an improvement on pumps already patented to me; it relates to that class of pumps in which the water is rst raised by atmospheric pressure. The objects of my invention are, chiefly, to produce a continuous instead of` an intermittent ow of water, and

to so construct the siphon through which the water is discharged that air will not accumulate in its highest point.

In the drawing, A B represent two cylin-r ders; C D,floating plungers, one in each cylinderg aI a', openings through each plunger;

b b', valves to close the openings a a. The

`space between the plungers and cylinders will be filled with water,which will serve as packing. The chamber or cylinder A communicates with the passage E, and the cylinder B communicates with the passage F. E and F are separated by the partition G, and both communicate withpthe outlet J `through the valve-chamber K. h h arevalves. H is the inlet-pipe; c, a valve, which closes the passage-way from H to the cylinder A; and c', a valve to close the passage from H tothe cylinder B. d d are bars to arrest the upward movement of the valves c c'. In this pump I 4use steam to create a vacuum, and also,when desired, to force the water from the cylinders,

the water being forced from and a vacuum being created in the two cylinders alternately, as follows: e e are pipes, through which steam `is Vadmited into the cylinders A B through the passages ff', and above the plungers C D d I is a walking-beam, supported upon a shaft having bearings in the sides or walls of the passages E F, one end of which shaft extends outsideof the wall, and has a bar or 1 leverattached thereto for the purpose of starting the pump, after which the operation will be automatic. g g are rods or bars placed within the steam-passages ff', of such length that when in the position shown in Fig. l one will extend a short distance into one cylinder, and the other side will be on a line with the y top of the cylinders. The ends of the beam I are inserted into the rods or bars g g. This beam also passes through the valvest' z", which valves open and close the openings u u and u u from the steam-passages g g' to the passagesE F. t' r are valves attached to the bars g g', for the purpose of opening and closing the steam-inlets. The rods or bars g g', the valves t fi, and the valves 7 r are all operated by the beam I. Any air which may be in the cylinders A B when the plungers rise will be forced `out through the openings u u u u into the waterpassages and carried out with the water, and, by means of these openings, the condensation of the steam may be more rapid. The beam I is located fwholly within the walls of the pump. To prevent the escape of steam from y ,Y

by the pressure ofthe atmosphere,I use a si-V phon, S, for a discharge-pipe. As in one of my former patents with this improvement, it is flattened at the top, (see Fig. 4, L5) and by this means I accomplish an important result.

When the siphon has the usual form, curved` top of the Siphon and thence into the cylinders 5 but, when the attened siphonis used, the air is broken up into small bubbles, so

that itstendency to rise is counteracted by the outtlowing current of water, and it cannot accumulate in the Siphon. Whether this theory is entirely correct I cannot say; but I know, from repeated trials, that the vpump will not work with the siphon made in the usual form, while it will work constantly and perfectly when the siphon is flattened at the top, as described and shown.

Operation.

Suppose the pump to be in operation, as shown in Fig. l, C is at the top of A and D at the bottom of B. C, ascending, comes in contact with the lower end of g, forcing it up, carrying up that end of I, opening the steamninlet from e, and closing the openings a a; at the same time the other end of the beam I was carried down, closing the steam-inlet from e', and opening u u. The parts being in this position, steam will pass'frem any suitable boiler through e and f to the top of the plunger C, which, by the pressure of the steam, will be forced down, forcing the water inthe lower part of cylinder A out through E K J, the valve h being opened and the valve c being closed at the same time the valve b will open and the steam in the upper part of B will condense, forming a vacuum. Water will beforced by the pressure of the atmosphere through pipe H, opening the valve c into the cylinder B, and D will be forced up to the top of B, and, coming in contact with g, will elevate the depressed end ofthe beam I, opening e, closing u u', closing e, and opening a u; at the same time the valve b will open and the steam in the upper part of A will condense; water will be forced into A through the pipe H and valve c, and steam passing through e g will force down D, forcing out the water on that side through F K J 5 the valve h being then open and h closed. This operation being constantly, repeated a continuous stream will be discharged.

With this pump water can be raised by at- Inospheric pressure from twenty-five to twentyeight feet, and may then be discharged at a steam-pressure equal to the first atmosphere; or it can then be forced to any reasonable height by the use of steam at the required pressure. pump with a force-pump, and also have a continuous flow of water. I only use the siphon when the water is to be raised not over twentyeight feet; when to be raised higher than that I use an ordinary discharge-pipe. By extending the long leg of the siphon the water will be discharged at a pressure less than that of the first atmosphere.

Instead of pivoting the rocking cup to the beam it may be held against the rubber by a spring and still have the rocking movement.

When this pump is working the attendant will know that the cylinders are filled at each stroke, and that the pump is doing its full work, because the plungers will not operate the rods g g unless the cylinders are filled.

What I claim as new is as follows:

l. The combination of the cylinders A B, plungers C D, each provided with a central passage and valve, inlet passage or chamber H, provided with the valves c c with the discharge-passages E F, and suitable devices for admitting steam to the cylinders, so that the water may be discharged above the pump and the operation performed partly by force and partly by suction, substantially as specified.

2. The walking-beam Lin combination with the discharge-passages E F and steam-chambers, when constructed and arranged to operate within the same, so as to dispense with any additional frame-work for its support, substantially as described.

3. The beam I, rods g g', valves i i and r r', in combination with the cylinders AB, plun g ers C D,inletpipe and valves H c c', and outlet-passages E F, substantially as and for the purposes specified.

4. The rubber spring 7c and rocking cup c, in combination with the valve i, substantially as and for the purposes specied.

5. The siphon S when flattened at the top,

substantially as and for the purpose specied.
